The chief thrust of the research has been directed towards the evaluation of polyacetylene (CH)/sub x/, the prototype conducting polymer as an electrode-active material in novel, rechargeable batteries employing nonaqueous electrolytes. The p-doped material, ((CH/sup +y/)A/sub y//sup -/)/sub x/, (where A/sup -/ is an anion) in conjunction with a Li anode, shows excellent discharge characteristics, e.g., very little change in discharge voltage with change in discharge current and a high power density. Its energy density is also good but it shows poor shelf life. When (CH)/sub x/ is used as a cathode (Li anode), which results in the formation of the n-doped polymer, (Li/sub y//sup +/(CH/sup -y/))/sub x/, during discharge, good discharge plateaus and power densities are obtained together with excellent shelf life and good recyclability. The energy density is, however only moderate. Cells employing an (M/sub y//sup +/(CH/sup -y/))/sub x/ (where M = Li, Na) anode and a TiS/sub 2/ cathode show very good discharge and recycling characteristics but their energy density is poor.
